Can you clarify what the USB chniargg cycle is for the cradle only. True/False; the USB input will only charge the cradle? True/False; the ipod, if just in the cradle (and not in the windshield holder as well) will not charge while in the cradle. The mode button on the back of the cradle, does it need to be in any particular position in order to take on charge for the cradle? (GPS, vs Off, vs Battery.)Thanks.
